From Docker to Podman

Podman is a tool that can run OCI containers and aims at being a drop replacement for Docker but with some differences

• no daemon
• rootless by default
• only run containers, do not build images

However, there a subtle differences that makes it hard to directly replace docker by podman.

Usage

The main difference with docker is that podman does not use a daemon. The consequence of that is that the containers are running with the user that started them.
